Alaska is so big, it could fit Texas inside twice

Image: Paxson Woelber

Sure, everything’s bigger in Texas… but where does that leave Alaska? The Last Frontier spans about 663,000 square miles , while the Lone Star State covers roughly 268,000 square miles. So yes, you could comfortably fit Texas inside Alaska twice, and still have room left over for California.

You could stack 10 Washington Monuments inside the Grand Canyon’s depth

Image: Sonaal Bangera

At its deepest point, the Grand Canyon plunges more than 6,000 feet. That’s more than a mile of height, to give you an idea. To put that in perspective, the 555-foot-tall Washington Monument could fit inside the canyon roughly ten times from top to bottom.

The Statue of Liberty’s sandal is the size of a small car.

Have you ever paid attention to the Statue of Liberty’s feet? Yes, they are visible, right next to the broken shackles at her base. You can’t stand next to the feet, of course, but if you could, you’d see that each sandaled foot measures about 25 feet long , which is a bit over the length of a Chevy Suburban.

The Empire State Building was built faster than a modern kitchen remodel

Image: Kit Suman

Did you know that one of the most famous buildings in the world was pretty much speed-built? Construction took just 410 days , starting in 1930 and finishing in 1931. This rapid progress was possible thanks to prefabricated steel parts and a workforce of roughly 3,400 workers each day. Nowadays, your average kitchen renovation takes 6 months to a year.

If the Earth were the size of a basketball, the Moon would be a tennis ball 24 feet away

Image: Anne Nygård

This is a fun way to illustrate the relationship between our planet and its satellite. If Earth were the size of a basketball (about 9.5 inches in diameter), the Moon would be roughly the size of a tennis ball (about 2.5 inches).

But they would be a whopping 24 feet away, about the length of a stretch limousine (or a Statue of Liberty sandal). This scale model helps explain just how far apart and disproportionate they really are!

A single cloud can weigh as much as 90 elephants

Clouds may not look heavy, but these giant beauties are surprisingly massive. Scientists estimate that an average fluffy cumulus cloud contains about 1.1 million pounds of water, which is roughly the weight of 90 adult African elephants .

You could fit 7 Yankee Stadiums inside the Mall of America

Image: David Vives

With over 5.6 million square feet, the Mall of America is one of the largest indoor spaces in the country . Imagine trying to meet your friends in just one of its 500+ stores!

The mall also features an indoor amusement park and an aquarium. To give you an idea, Yankee Stadium covers roughly 800,000 square feet. You could fit about seven of them within the Mall of America.

A hummingbird flaps its wings faster than a car engine runs

Hummingbirds beat their wings between 50 and 80 times per second , roughly eight times faster than the revolutions per second of a typical V8 engine at idle. No wonder they have enough force to seemingly fly in place!

Comparing lightning bolts with defibrillator shocks

Image: chutipon Pattanatitinon

The energy in lightning bolts can vary, but it’s not uncommon for them to unleash 5 billion joules . Roughly, a biphasic defibrillator delivers about 200 joules in a single shock. And, to give you an idea, it takes roughly 50,000 joules to toast a single slice of bread.

Yellowstone sits on top of a supervolcano the size of Rhode Island

Image: Denys Nevozhai

You might have heard of Yellowstone’s supervolcano and how tourists leave mesmerized by the geysers, hot springs, and wildlife.

But the size of its caldera is even more astonishing: it stretches 20 by 45 miles , covering nearly 1,350 square miles. That’s roughly the same area as Rhode Island, the smallest U.S. state.

Niagara Falls could fill an Olympic pool in less than a second

Image: Hadi Yazdi Aznaveh

A standard Olympic-size swimming pool holds about 660,000 gallons. Niagara Falls, however, pours roughly 700,000 gallons of water every second, meaning it could fill a pool in under one second, approximately 0.94 seconds to be exact.

If you were filling the same pool with a standard hose, it could take about 19 days .

Robert De Niro vs Mickey Rourke

Image: Vitruvian Badr

At first glance, it was the typical 1980s film set. But when Robert De Niro and Mickey Rourke worked together in Angel Heart , their differences in style weren’t just noticeable; they were combustible. De Niro, famous for disappearing into his roles with a strict Method approach, didn’t always mesh well with Rourke’s more unpredictable, improvisational take.

According to lore, all hell broke loose when Rourke decided to ignore De Niro’s suggestions for a scene. What was supposed to be a straightforward shoot turned into multiple takes, frustrating not just the two stars but the entire crew. The altercation quickly became Hollywood gossip, with insiders saying it was a classic case of two strong personalities refusing to give in.

2

David Letterman vs Jay Leno

Image: John-Mark Smith

Who deserved the late-night crown , Letterman or Leno? For years, Americans were unable to settle the debate. On screen, both comedians exchanged polite words and even jokes, but behind the curtain, the situation was a little more complicated.

Reporters loved to stir the pot, writing headline after headline about which funnyman truly deserved the throne. Viewers, meanwhile, treated it almost like a sporting match, tuning in to see who would come out on top. In truth, much of the "feud" was blown out of proportion, yet the friendly jabs and constant comparisons managed to keep audiences entertained.

3

Dean Martin vs Jerry Lewis

Image: anncapictures

On stage, there were only gags, music, and applause. But behind the scenes, Dean Martin and Jerry Lewis were falling apart. Martin often felt stuck playing the calm, serious foil while Lewis stole all the laughs with his wild, over-the-top routines.

Over time, that imbalance created real tension. After starring in 16 hit films together, the famous duo finally called it quits. Their split was so final that they didn’t exchange a word for two full decades. Fans were stunned when they eventually patched things up later in life, a reminder that even the biggest comedy legends aren’t immune to bruised egos and long silences.

Olivia de Havilland vs Joan Fontaine

Image: cottonbro studio

Few family feuds reached the heights of Olivia de Havilland and Joan Fontaine’s legendary rivalry. The sisters were competitive long before the bright lights of Hollywood, each vying for their mother’s attention. Once both became movie stars, the bad blood only grew stronger.

In 1942, the two actresses were even nominated for Academy Awards in the same category. Fontaine ended up winning and later claimed her older sister pulled her hair during the ceremony. That incident became one of Hollywood’s most talked-about snubs. Their quarrel stretched on for decades, marked by jealousy, pride, and the kind of family drama that the public can’t get enough of.

5

Elton John vs Madonna

Image: HubertPhotographer

It may sound like sensational news, but Elton John once declared Madonna’s Bond theme "the worst ever." From that point on, the two megastars exchanged sharp words through the press, with Elton poking fun at her performances and Madonna brushing off the criticism with icy charm.

Reporters loved every jab, turning their spat into tabloid gold. Though they occasionally patched things up, the rivalry lingered. Even music royalty can squabble just like the rest of us!

6

Marilyn Monroe vs Jayne Mansfield

Image: WikiImages

In the 1950s, Hollywood had room for only so many platinum blondes, and Marilyn Monroe was already the reigning queen. When Jayne Mansfield came to light with her hourglass figure and playful charm, the press quickly dubbed her "the next Monroe."

Marilyn, who guarded her image carefully, bristled at the idea of a copycat stealing her thunder. Meanwhile, Mansfield leaned into the comparisons, showing up at events in daring outfits and orchestrating photo ops that guaranteed headlines. The result was a highly public rivalry that fascinated fans, turning every red carpet into a showdown.

7

Johnny Carson vs Joan Rivers

Image: Debby Hudson

One phone call never answered, one friendship lost forever. Joan Rivers owed much of her early success to Johnny Carson, who gave her a career-changing boost as a regular guest on The Tonight Show . For years, she was seen as his comic protégé, someone he personally championed. But when Rivers accepted an offer to host her own late-night program, Carson viewed it as a betrayal.

He cut off contact immediately, refusing to take her calls, and the friendship that once seemed unbreakable collapsed overnight. Fans were stunned to see the bitter end of what had appeared to be a classic mentor-and-student bond. The silence lasted all their lives.

8

Debbie Reynolds vs Gene Kelly

Image: Kazuo ota

When Debbie Reynolds starred in Singin’ in the Rain , she was a 19-year-old performer stepping into a major role for the first time. Gene Kelly, already an established star, demanded flawless performances and wasn’t known for his patience. Reynolds later recalled long hours of grueling rehearsals, where Kelly frequently criticized her every move, reducing her to tears.

Though their discord was rooted more in his high standards than personal dislike, the experience marked a harsh introduction to Hollywood for the young actress. Today, their behind-the-scenes tension is remembered as both a glimpse into Kelly’s tough reputation and a reminder of the enormous pressures that came with working alongside legends.

Orson Welles vs William Randolph Hearst

Image: William Warby

When Citizen Kane hit the screens, it wasn’t just a film debut; it was the spark of one of Hollywood’s fiercest battles. William Randolph Hearst, the media tycoon who saw too much of himself in the story, launched an all-out war against Orson Welles.

He tried to bury the film before it could reach audiences, banning ads in his papers and fueling smear campaigns. What began as a clash of egos grew into a cultural showdown, forever linking their names to both scandal and cinematic history.

10

Frank Sinatra vs Marlon Brando

Image: Brett Sayles

If you watch Guys and Dolls today, all you’ll see is glamour. In reality, the shooting was pretty stressful: Sinatra craved efficiency, Brando thrived on slow-burning performance. Brando’s Method acting tested Sinatra’s patience, as Ol’ Blue Eyes favored efficiency and clean, polished takes.

Rumors of heated exchanges and icy silences hit the media, and by the final days of filming, the pair were barely speaking. What should have been a classy production became notorious for its behind-the-scenes tension, adding an extra layer of drama to the musical classic.

11

Bette Davis vs Joan Crawford

Image: Nathan DeFiesta

So iconic was their hatred that it later inspired documentaries and TV series. Davis and Crawford didn’t just feud; they redefined what a Hollywood rivalry is. For decades, the two icons sparred over leading roles, critical acclaim, and public adoration.

Gossip included backhanded insults, stolen lovers, and outright sabotage during productions. When they finally shared the screen in 1962’s What Ever Happened to Baby Jane? , the film’s unsettling tension was magnified by their very real animosity.

12

Chevy Chase vs Bill Murray

Image: Aleks Dorohovich

In the early days of Saturday Night Live , Chevy Chase and Bill Murray were usually at each other’s throats. Chase’s sharp, polished delivery often clashed with Murray’s more offbeat, improvisational style, and the tension spilled offstage.

Reports of heated arguments (and even a near brawl backstage) turned their working relationship into one of the show’s most notorious conflicts. Though both later moved on, their rocky career start stands as a reminder of how fragile chemistry can be in comedy’s spotlight.

Superman

It’s a bird! It’s a plane! No, it’s our first entry to this article! For many, the "Man of Steel" is the epitome of an American superhero : Not only is he one of the oldest superheroes still in circulation, but he is also a die-hard defender of truth, justice, and the American Dream.

Superman’s story has been told countless times, but here’s a quick summary just in case: Born in the far-away planet of Krypton, Kal-El was sent to Earth as a baby, where he was adopted and named Clark by Martha and Jonathan Kent. Young Clark discovered his amazing powers at an early age, and grew to become Superman, the "Man of Tomorrow".

2

Batman

Image: Obi - @pixel8propix

Right along with Superman, Batman is perhaps the world’s most famous superhero. What’s interesting is that, although both superheroes are equally iconic, they couldn’t be more different: While Superman is a superpowered public figure, who regularly engages with the American people in a friendly manner, Batman is a dark and mysterious figure , who fights evil-doers from the shadows and has no superpowers other than his superhuman determination (and his fair share of high-tech gadgets!).

Bruce Wayne, the man behind Batman, has a backstory that’s almost as dark as his alter ego: Born into the wealthy Wayne family, Bruce's parents Thomas and Martha were tragically murdered when he was eight years old. Determined to fight the evil that took his family away from him, Bruce spent his life and fortune to become Batman, Gotham City’s Dark Knight.

Spider-Man

Up until the emergence of this beloved superhero, whatever our childhood heroes did for a living was not particularly important. For instance, Clark Kent is a Pulitzer-winning reporter, while Bruce Wayne comes from an extremely wealthy family. However, what separates Spider-Man from the rest (besides his groundbreaking arachnid powers ) is the fact that he had to juggle his superhero activities with his education and part-time photography job. In a sense, Peter Parker was the first to show us that superheroes could also come from struggling backgrounds.

When he was first published in 1962, Spider-man was also one of the youngest superheroes out there: At age 15, Peter Parker was bitten by a radioactive spider, which gave him his amazing and uncanny abilities . Spiderman can climb up walls, swing around skyscrapers, and sense danger with his trusted "Spider-sense".

Iron Man

Even before being immortalized by actor Robert Downey Jr . in what’s probably the most lucrative film franchise in history, Iron Man was already one of Marvel’s most recognizable superheroes. Created by Stan Lee and Jack Kirby in 1962, this hero drew his abilities from machines’ raw power and mankind’s insurmountable ingenuity.

Unlike many superheroes, Tony Stark’s backstory is characterized by his search for redemption: Born into a wealthy family, he sought to dismantle his family’s lucrative arms-dealing business after he witnessed first-hand the horrors his products caused. Tony used his superior intellect to design and construct his iconic "Iron Man" suit , a metal exoskeleton armor that grants him flight, superhuman strength, and access to repulsor blasts and other high-tech gadgets.

5

Wonder Woman

Comic books are usually considered a boys’ club, but the truth is that not all superheroes are male. We could have chosen from a myriad of iconic female heroes, but we finally settled on one of DC’s powerhouses : Wonder Woman. Though she recently saw a resurgence in popularity thanks to her 2017 jump to the big screen, this Amazonian warrior has always been a force to be reckoned with.

Princess Diana comes from the island of Themyscira, a fictional island home to the warrior race of the Amazons. Wonder Woman’s strength is almost unmeasurable, and she also possesses the gifts of flight, speed, and invulnerability. She is also armed with her indestructible bracelets and her iconic "Lasso of Truth" , which forces those trapped in it to reveal their secrets. Fun fact: Wonder Woman’s creator William Moulton Marston invented the lasso while working on his other groundbreaking invention, the modern lie detector.

The Hulk

When Robert Louis Stevenson published his 1886 novella Strange Case of Dr. Jekyll and Mr. Hyde , he wasn’t aware that he was also creating the basis of one of the world’s most iconic superheroes. While The Hulk is known mostly for his brutish strength and uncontrollable rage , this seemingly simple superhero also deals with mankind’s fear of its own dark side, and what happens when this more violent aspect of ourselves is let loose.

You are probably aware of the Hulk’s origin story: Dr. Bruce Banner, a brilliant scientist, was hit with a heavy dose of gamma rays after an experiment went wrong. This accident transformed Dr. Banner, turning him into the green-skinned, rampaging Hulk whenever his anger reaches a breaking point. While his powers are definitively destructive, over the years the Hulk has turned into a force of good, and a superhero in his own right.

7

X-Men

Image: Erik Mclean

The first superhero team to make it to this list, the X-Men introduced the world to "mutants", the next step of human evolution. Mutants displayed fantastical powers from an early age, although some of their mutations made them look threatening or off-putting to society. In the end, prejudice was one of the X-Men’s greatest foes, and a recurring theme throughout this series’ 60 years.

The X-Men saw a resurgence in popularity throughout the 90s and early 2000s, in part thanks to an amazing TV adaptation and a series of films produced by 20th Century Fox. Among the team’s most famous roster, we have the X-Men’s leader Cyclops (who can shoot energy beams from his eyes), Storm (a mutant that can control the weather), and Wolverine (who can heal almost instantly, and whose skeleton was reinforced with an unbreakable metal).

8

The Flash

Image: Joel Muniz

Superman might be "faster than a speeding bullet", but the Justice League’s undisputed speedster is definitively The Flash. While his superspeed power might seem simple, it is anything but: Flash is connected to an extradimensional energy source known as "the Speed Force", which allows him to move, think, and react at superhuman speed.

While the first character to take this name was Jay Garrick in 1939, the Flash most people are familiar with is Barry Allen, who was granted the powers of the Speed Force after an experiment gone wrong. His red suit and lightning-fast reflexes have made him one of the most recognizable heroes in history.

9

Thor

Image: Manuel Salinas

As we mentioned before, many believe superheroes to be our modern myths. However, what’s fascinating about this superhero is that it perfectly combines the standard characteristics of a comic book hero with the amazing feats of the most adventurous Nordic god . Thor Odinson, Marvel’s iconic otherwordly protector, is definitively the best of both worlds.

When Jack Kirby and Stan Lee created Thor in 1962, they kept many aspects of the Nordic deity: Marvel’s Thor has super-human strength, can control thunder, and is always aided by his enchanted hammer, Mjolnir . However, the modern adaptation added a new layer: Deemed too arrogant by his father Odin, Thor was banished to Earth, where he became our planet’s trusted guardian.

10

Captain America

Image: Marjan Blan

We’ll end this list with an American icon. In 1940, worried by the advancement of WW2, writer Joe Simon and artist Jack Kirby sought to create a superhero that would both encompass the values of American life and fight to preserve peace and justice in the free world. And with that, Captain America was born.

The Captain’s story has been told many times: Steve Rogers was a frail but brave American who was administered a "Super Soldier" serum that gave him super-human speed, strength, and reflexes. However, one of Cap’s superpowers that is usually overlooked is his tenacity, both in comics and in real life: After being canceled in the 1950s, this character was brought to life once again by Stan Lee, who designed the modern version of Captain America that we now know and love.
